An Ionia man pleaded not guilty Tuesday at his arraignment on child pornography charges in Ionia County 8th Circuit Court before Judge David Hoort.

Mark Moon, 30, faces three counts of possession of child sexually abusive material and one count of using a computer to commit a crime. One additional count was dismissed.

Each of the counts regarding possession of material carries a penalty of up to four years in prison and/or up to $10,000 in fines. The count regarding the computer use carries a penalty of up to seven years and up to $5,000 in fines.

The charges against Moon stemmed from incidents that took place in Ionia between January and March.
